Abbot Nutrition says baby formula production has resumed at the Michigan plant whose February shutdown over contamination contributed to a national shortage.
Damage from severe thunderstorms had halted Sturgis plant operations in mid-June after just two weeks of renewed production.
Abbot says EleCare, a specialty formula, is being made at Sturgis following a July 1 reboot and that Similac production will resume as soon as possible.
Abbott is one of just four companies that produce 90% of U.S. formula.
Its recall in February of several leading brands squeezed supplies already strained by supply chain disruptions and stockpiling during COVID-19 shutdowns.
